Climate Change and a New Archaeology

Otzi (4th millennium BCE), the iceman found in the melting glacial ice of the Italian Alps in 1991, is ushering in a new field of archaeology dubbed glacial archaeology, though the label is too restrictive to delineate the archaeological revelations being made by climate change. Glaciers are melting and receding, revealing artifacts, bodies, and even viruses frozen deep in the ice for millennia (Solis-Moreira 2023). Otzi is the dean of climate change archaeology, and it is occurring in more environments than glaciers and ice fields.

Some 10% of the earth is covered in glacial ice, preserving trapped objects when they first froze. Glaciers surrendering their prehistoric vaults are occurring world-wide, including the Alps, Norway, Siberia and Yellowstone National Park. Artifacts recently revealed by glacial retreats include arrows with feather fletching and hafted lithic points (1000 BCE), iron age skis (700 CE), prehistoric animals (e.g., wooly mammoths (28,000 BCE), penguins (1200 CE), and other species of prehistoric interest. Glaciers and ice patches have also yielded organic artifacts – wood, textiles and vegetable fiber, including baskets. The icy surrender of such diverse artifacts is insightful, but the melting snow and ice offer poor substrate or stratification for research and can leave cultural materials from different epochs together. Finally, archaeologists must be prompt in surveying melting glacial surfaces routinely or cultural materials may be washed away (Solis-Moreira 2023).

Global warming is not the only condition that exposes and threatens archaeological materials. Climate change is now causing sea rise and inordinate flooding that threatens archaeological sites, known and unknown, on coastal low lands (Whigham 2023). Extreme high tides put coastal sites under water for prolonged periods and contribute to the deterioration of subsurface materials and features, compromising the knowledge such prehistoric sites might yield. The damage goes unseen but is happening, nonetheless.

Hurricanes are intensifying in frequency and strength, also a result of climate change, bringing with them damaging erosion, tidal surges and winds, all with the potential to expose cultural materials, including burials of coastal sites. Hurricane Nicole, in 2022, unearthed at least six burials on Chastain Beach, Hutchinson Island, Florida. Locally, it became known as skull beach, an attribute made by the salvage archaeology done there. Hurricanes Sandy (2012) and Dorian (2019) exposed similar graves (Skinner 2022). Many unknown prehistoric sites are lost without recognition or acknowledgement.
